I try to stay in the moment and smile without holding on to a memory in the past or craving for something in the future. It is challenging to do, harder than I had thought initially. However, when it works, I can feel the stillness, even if momentarily.
When I am in that space and not in my thinking mind, I can relate to the idea of happiness, as explained in this article.
In the meantime, I remind myself to find reasons to smile no matter what the circumstance. It connects me to that tranquil peace and happiness and abundance from inside.
